Abstract

Climbing perch is one of economically-valued local fish in Indonesia, particularly in Borneo, Sumatra, and Java Islands. The fish has the potential to be developed as freshwater aquaculture species. The purpose of this experiment was to evaluate the production performance and blood profile of climbing perch cultured in peat pond with different stocking densities. The research was conducted in Kereng Bangkiray Village, Sebangau District, Palangkaraya City, Central of Borneo. Nine fish ponds sized 5.0 m x 5.0 m x 1.5 m were used. Nets with a mesh size of 1 cm measuring 2.0 m x 1.5 m x 1.0 m was installed in each fish pond for the experiment. The treatment consisted of different stocking densities, namely 15 fish/m2, 30 fish/m2, and 45 fish/m2. Fish with the body weight of 20 ± 1.25 g were used. Fish were cultured for four months. An artificial diet containing 30% protein was given with a feeding rate of 5%. The experiment was designed in a complete randomized design. The result showed that the production performances (i.e. survival, specific growth rate, absolute weight, and biomass) were significantly higher at the densities of 15 and 30 fish/m2 than that of 45 fish/m2 (P<0.05). Blood profile such as glucose, erythrocyte, leucocyte, and hemoglobin were higher at the density of 45 fish/m2 except for hematocrit which was higher at the densities of 30 and 15 fish/m2. Water quality parameters such as dissolved oxygen, nitrite, nitrate, and ammonia at the densities of 15 and 30 fish/m2 showed better values than that of 45 fish/m2 stocking density. To optimize the productivity and maintain the optimum water quality condition, the optimal stocking density for climbing perch culture is suggested at 30 fish/m2.

Abstract

Mud crab culture relies heavily on trash fish as the main source of feed ingredients. Artificial diets have been developed for mud crab and most of them have high content of fish meal. The increasing cost and demand of fish meal has encouraged feed manufacture to search for cheaper alternative protein sources such as plant protein. There is an urgent need to find suitable alternative protein sources to reduce the dependence of fish meal in mud crab diet. The objective of this study was to develop compounded feeds for juvenile of mud crab with reduced fish meal content, and as an alternative of trash fish feeding. For that reason, the experiment was done. Experimental diets were fish meal, 20% of soy bean (20% SBP), 40% of soy bean (40% SBP), 20% of corn gluten (20% CGP), and 40% of corn gluten meal protein (40% CGP). Average initial mud crab body weight of 0.65 ± 0.03 g was fed experimental diets for 56 days. The result showed that dietary fish meal protein can be replaced by 20% of soy bean and 20%–40% of corn gluten proteins for mud crab (Scylla paramamosain) diet. Thus, it can arguably be concluded that soy bean and corn gluten proteins are the alternative protein sources to partially replaced fish meal.

Abstract

Disease surveillance programs will provide updated information on the distribution of diseases which allows proper development of mitigation and prevention strategies. WSSV and IMNV viruses are the most threatening diseases in shrimp and have affected the global shrimp farming industries. The present study was conducted to investigate the prevalence of WSSV and IMNV in three different locations of shrimp farms of South Sulawesi, West Nusa Tenggara and West Jawa. Samples of shrimp Litopenaeus vannamei were randomly collected from 20 active shrimp farms in the locations and five samples of postlarvae (PL) that were stocked in ponds. Tissue samples of the shrimp and whole body of PL were preserved in ethanol 90% for analysis. Determination of WSSV and IMNV were carried out by the mobile IQTM WSSV and IQTM IMNV Kit POCKIT Systems. The results showed that the prevalence of WSSV was 30% (6/20) and IMNV was 20% (4/20), while on PL was 40% (2/5). The result revealed that the South Sulawesi (Takalar) samples were positive only for WSSV while West Java (Panimbang) samples were positive only for IMNV. A follow-up study predicted that both viruses were transmitted from the PLs. The present study clearly confirmed that viruses were transmitted from PLs that were not free from either WSSV or IMNV. Therefore, a biosurveillance program is strongly recommended to be implemented in order to avoid the spread of the viral disease to other locations within Indonesia.

Abstract

This study aims to know the potential of forest honey Apis spp. from Timor Island as antibacterial on pathogenic bacteria Aeromonas hydropilla and Vibrio alginolyticus in cultured fish, through testing of active compound, total glucose, pH and water content of the honey, that play the role in antibacterial mechanisms in honey. Chemical content of the honey was examined for alkaloid using Culvenor-Fiztgerald method, saponin with foam test, terpenoid and steroid with Lieberman-Burchard method, tannin with addition of FeCl3, and flavanoid addition of HCl and Mg powder. Total glucose was measured using spectrophotometer, water content with gravimetry, and pH with pH-meter. The antibacterial activity  test of the honey was done using disc method without dilution. Results showed that all forest honey from Timor Island contained alkaloid, saponin, steroid and terpenoid, except that Kefa honey did not hold steroid and terpenoid. Water content of the honey ranged from 15.70% to 26.65%, total glucose of 71.16% to 80.58%, and pH of 3.84 to 4.06. The forest honey had also antibacterial activity against A. hydropilla and V. alginoliticus with different inhibition zone.

Abstract

Taxonomy of mud crab species under the genus Scylla has been misidentified for several years due to their high morphological similarity. In Indonesia, some reports concerning mud crab have been published with misleading identification results where the species under the genus Scylla all named as Scylla serrata. The study was conducted to reconfirm the validity of species in the mud crab genus Scylla collected from Balikpapan mangrove, East Kalimantan, Indonesia and to analyze the genetic variation of the first generation (G-1) offspring, based on mitochondrial 16S rRNA sequence. The animal test used for species identification was a representative sample of mud crab. Ten of the G-1 crablet were randomly sampled for genetic variation analysis. Fragment of the 16S rRNA gene was isolated by PCR technique and purified for sequencing purpose. The mtDNA sequences were analyzed using Genetyx, BLAST-N, and DnaSP to get a consensus sequence, similarity index, haplotype and sequence diversity, and the number of haplotypes. The results showed that the 16S rRNA gene was successfully isolated with a single band in size of approximately 600 bp. The mud crab morphologically identified as Scylla tranquebarica was genetically confirmed as a species of S. tranquebarica. High haplotype diversity (0.9254) and low nucleotide diversity (0.1256) were revealed in the G-1 mud crab population, while the number of haplotypes was 7.5.

Abstract

Nervous Necrosis Virus (NNV) is a devastating viral disease in marine aquaculture, causing significant economic losses worldwide, including in Indonesia. The virus mainly infects larvae and juveniles of marine fishes. This study aimed to determine the effectiveness of a recombinant vaccine from betanodavirus coat proteins expressed in Escherichia coli fish against NNV infection in hybrid grouper. An RNA2 capsid protein was selected and used as the recombinant vaccine. NNV-RNA2 gene was inserted into the protein expression system vector of pET SUMO and cloned in cells of bacteria Escherichia coli strain BL-21. The results of blast homology analysis exhibited that the amino acid sequence of the NNV-RNA2 showed high similarity with Lates calcarifer encephalitis viral coat protein gene. E. coli expressing NNV-RNA2 protein was inactivated using 0.03% formalin and mechanically inactivated by freeze-thaw and sonication methods. The inactivated recombinant E. coli vaccine was then injected intramuscularly into hybrid grouper juveniles (single vaccine). Subsequently, the juveniles were challenged with NNV at 7, 14, and 21 dpv (days post-vaccination). Injection of 0.1 mL sterile PBS served as the control. Single vaccine applications using formalin-inactivated vaccines resulted in higher antibody titers than those of mechanically-inactivated vaccines. Both vaccines were only able to increase antibody titer up to 7 dpv. Therefore, re-vaccination (booster vaccine) was done on day-10 after the first vaccination using a formalin-inactivated vaccine. The booster vaccine could protect hybrid grouper against NNV (P<0.05) at four weeks post-vaccination. However, the mortality of vaccinated and control fish was not significantly different (P>0.05) after challenged with NNV for six weeks after. This recombinant vaccine has the potential to be developed into a polyvalent vaccine by combining viral and other bacterial vaccines in future research.

Abstract

The effects of live transportation on the immune modulation of wild and ocean-ranched greenlip abalone (Haliotis laevigata) were evaluated. Samples of abalone were collected both in autumn and winter in Flinders Bay, Augusta, Western Australia, and land transported for 6 (six) hours. Several immunological parameters were assessed, including survival rate, total haemocyte count, osmoregulatory capacity, phagocytic rate, lactate level, and glucose level. The results indicated that the abalone samples collected in the two seasons showed different physiological responses; the winter samples were more responsive to transportation than the autumn samples. Transportation stress significantly increased total haemocyte count and osmoregulatory capacity of the winter samples, suggesting an immune stimulation. This stress also triggered an immune suppression, causing the phagocytic rate and lysosomal stability to significantly decrease after transportation. Lactate levels in the winter samples decreased significantly after transportation, possibly indicating the transition from a stressed to normal state, during the period of recovery. The constant level of glucose before and after transportation in both seasons showed that it was the least sensitive indicator used in this study. In general, there was no difference in the immune modulation parameters between wild and ranched abalone in either of the seasons sampled. However, in the autumn samples, there were significant differences (P<0.05) in haemocyte count and osmoregulatory capacity of the wild and ranched samples collected from all sites. These differences did not form a consistent indicator trend between the sites from the two sample sources. Therefore, the results do not raise any immediate concern that ranched abalone were differently stressed to those from the wild. The results in present study could serve as useful data in developing the live transportation method of greenlip abalone.

Abstract

Asian redtail catfish Hemibagrus nemurus is one of the prospective aquaculture commodities in Indonesia. However, there are still shortcomings in completing the domestication of this species. As such, this study was conducted to observe the growth of Asian redtail catfish at different stocking densities. Fish (body weight (BW) of 21.62 ± 0.57 g) were stocked in nine different floating nets (dimension: 2 m x 2 m x 1 m) inside a concrete pond (40 m x 20 m) with three stocking density treatments (10, 15, and 20 fish/m3). Each treatment consisted of three replicates. Growth data were collected every 30 days during 120 days of rearing period which included weight gain (WG), specific growth rate in body weight (SGRBW), average daily growth (ADGBW), biomass gain (BG), feed conversion ratio (FCR), and survival rate (SR). Measured water quality parameters during the experiment consisted of temperature, pH, and dissolved oxygen. The results showed that the best growth performance was achieved by fish at the stocking density of 15 fish/m3 compared to that of fish with the stocking density of 10 and 20 fish/m3. The FCR value of fish at the stocking density of 15 fish/m3 was also significantly better than those of 10 fish/m3 and 20 fish/m3 (P<0.05). The survival rate in each treatment was not significantly different (P>0.05). This study suggests that the optimal stocking density for Asian redtail catfish fingerlings is 15 fish/m3, beyond that value, growth reduction might be expected. Further research is needed to observe its optimal stocking density in different culture systems.

Abstract

High production costs in grouper nursery can be caused by the use of large fingerlings size and long rearing times. The purposes of this study were to evaluate the culture performance and economic profitability of “cantang” hybrid grouper juveniles reared at different initial stocking sizes and nursery periods. This research lasted from September to December 2017 in one of small scale hatcheries in Buleleng, Bali, Indonesia. This study consisted of two experimental treatments; the first treatment was different initial stocking sizes (body weight and total length) of 0.50 ± 0.07 g and 3.0 ± 2.1 cm; 3.50 ± 0.67 g and 5.0 ± 1.9 cm; and 6.10 ± 0.91 g and 7.0 ± 2.3 cm. The second treatment was different nursery periods with the following arrangement: 15, 30, and 45 days (initial body weight and length of 0.54 ± 0.067 g and 3.0 ± 0.09 cm, respectively). The stocking density in all treatments was 1,000 fish reared in a 2 m x 2 m x 1 m concrete tank. The observed culture performance parameters consisted of survival rate (SR, %), daily growth rate (DGR, g/day), and feed conversion ratio (FCR). The calculated economic profitability parameters were net profit, return-on-investment (ROI, %), and return cost ratio (R/C). The highest culture performance was achieved by the juveniles reared using the largest initial stocking size and longest nursery period. This was in contrast with the economic profitability, in which smaller initial stocking size and middle nursery period had resulted in the highest profit. Based on the culture performance and profitability considerations, the suggested combination of initial stocking size and nursery period for cantang fingerlings is 3.0 ± 2.1 cm initial stocking size and 30 days rearing times.
